Question:

If the universe is an adiabatic system, why does the entropy universe always increase?

What happens when the entropy universe is maximum, 1?

Thermodynamic Process

When a system is brought from an initial condition to the final state in thermodynamic equilibrium the processes that are carried out on that system are known as a thermodynamic process.

Answer and Explanation:


The expression for the change in entropy of the system is,

{eq}\Delta S = \frac{{\Delta Q}}{T} {/eq}

Here, the temperature is {eq}T {/eq}, and the heat transfer rate is {eq}\Delta Q {/eq}.

The temperature of the universe keeps decreasing as the universe is always expanding and by considering the above expression it can be said that the entropy of the universe always increases.


If the entropy of the universe reaches the maximum limit all the available energy will reach the areas where the temperatures are low.
